JOHN IVENSING,

OF MILWAUKEE, WISCONSIN, ASSIGNOR OF ONE-THIRD TO ANTHONY V. KLEFISH, OF SAME PLACE.

COMBINED PIPE-WRENCH, MONKEY-WRENCH, AND FLANGE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 494,310, dated March 28, 1893. Application filed May 23, 1892- Serial No.433,946. (No model.)

ing drawings, which are apart of this specification.

My invention has relation to improvements in combined pipe and monkey wrenches and flange holders.

' The object is to provide asimple tool or implement of this character, capable of performing its work in a most efficient manner, and involving simplicity as well as ease and readiness of adjustment.

With the above object and others in view the invention consists in the improved construction and combination'of parts as hereinafter more fully set forth.

In the accompanying drawings, Figure 1, is a face view of my improved tool or implement, a portion of the stock being broken away. Fig. 2, is a view at right angles to Fig. 1, certain parts beingbroken away to more clearly illustrate the interior arrangement. Fig. 3, is a transverse section on the line 33 of Fig.1; and Fig. 4, is a detail view of an ordinary flange joint or union, which will more fully disclose one of the applications of my invention.

Like letters of reference designate like parts throughout the several views.

Referring to the drawings, the letter A designates the stock, forming the relatively fixed jaw of the monkey wrench. The stock is apertured throughout its entire length, the lower portion of this aperture being circular in form and the upper portion rectangular, the rectangular opening merginginto the cir- 'cular at the medial point a, which forms an inclined seat.. A rod B turns in the aperture of the stock, one end of said rod being screw threaded for a desirable distance and immediately below the threads provided with an enlargement, b, conforming, and adapted normally, to rest upon the seat a. of the stock.

The letter 0 indicates the movable jaw of the monkey wrench, said jaw provided with a rectangular shank D,-passing into the rectangular portion of the opening of tho fixed jaw. This shank isprovided with a screw threaded recess, d extending from its inner end outwardly for the greater portion of its length, and receiving the threaded portion of the rod B.

The movable jaw, 0, above referred to, is

provided upon its outer surface with a recess,

'0, in whichis secured a serrated plate E, the

function of which will hereinafter -fully appear.

'. This monkey wrench is operated by turning "of rectangular form, adapted'to surround the stock A. This collar is held in adjusted position upon said stock means of. a thumb screw G and is provided with lateral extensions g, g, having recesses or cavities g g, therein. In one of these cavities is pivotally secu red, by means of a bolt H, a jaw I, adapted to form one of the gripping jaws of the device when used as a pipe wrench. The inner end of this jaw is beveled, as indicated at i, and through the lateral extension of the collar passes an adjusting screw J, which is adapted to act against said beveled end, and rotate the jaw upon its pivot bolt. A spring K has its free end bearing against the pipe wrench jaw, I, so as to hold it normally in the position shown in Fig. 2. The recess 9' in the opposite lateral extension of the collar, has also pivoted therein upon a bolt L, a spring dog M, said dog also having its inner end beveled to provide for its adjustment laterally by contact therewith of the end of an adjusting screw N. The inner edge of this dog is toothed or serrated, said teeth or serrations engaging similar teeth on thecontiguo us edge of stock'A.

The movable jaw C, pipe wrench jaw I, and spring dog M are each provided with pins 0 extending transversely therethrough, the pins upon one side thereof being of less diameter than those upon the opposite side.

From the foregoing description, the application of my device as a monkey-wrench will be readily understood. It will of course be apparent that if desired, when thus used the collar F and its attached parts may be removed from the stock A by merely loosening thumb screw G. When it is desired to utilize the same as a pipe wrench, the movable. jaw I, may be adjusted by loosening thumb screw G which retains collar F in place upon the stock, and sliding said collar to the proper position in order to have the wrench jaw rasp i m y the pinesh wn in g-la designated by reference letter P; The movable jawO of the monkey wren,ch, also serves as the inner jaw to the pipe wrench, theserrated plate E ,holding'the pipe fili l ly in place.

In Fig. 4, I have illustrated an ordinary flange joint or union, .Q, such as that of pipes-wherethe connecting pieces have pe rat flange by whic the pa ts arei bolted together. The ordinary way of 211016: ing these joints or unions when'being taehed to the pipes is not entirely satisfactory, and entails considerable labor. By provid' ng he p n- 0, ho ev whic a made to engage the perforations of the flange,

the latter is most conveniently and firmly held while. being adjusted in the manner just pointed rent. The, jaws land M are adjusted I outwardly by means of the, screws bearing against the beveled ends thereof so as to bring the pins into alignment with the perforations while the jaw O is adjusted outwardly by means of rod 13 in order to bring its pin intoalignment with the appropriate.

perforation. By providing pins of different diameters upon opposite sides of the several jaws, these may be made to fit perforations of different sizes, and the implement thus adapted for holding difierent sized flanges by merely reversing the position of the tool.

Having thus described my invention, what I claim, and desire to secure by Letters Pat ent of the United States, is,-

1. The combination, of a stock, having its upper end extended laterally to form a fixed jaw, a shank movably connected with the stock, the upper end of said shank provided with alaterally-extending jaw, the outer face i of said jaw forming the lower jaw of the pipe wrench and the inner face thereof the uppen jaw of the monkey-wrench, anda jaw pivoted to the stock and longitudinally adjustable thereon, the upper portion thereof being curved to form the upper jaw of the pipewrench, substantially as setforth.

2. The combination, of awrench, the movable jaw thereof provided with a pin, an adjustable collar upon the stock of the wrench,

said collar provided with lateral recessed ex-- tensions, and spring'pressed jaws pivoted in said recesses, each provided with projecting P n sub tan ia ly as t orth.

*lhe ombina i n, of a w en the m able jaw thereof provided with pinsof din-(erent: sizes upo opposite sides ther of, an adj ustable collar upon the stock of the wrench aid olla provide i h la e-re r ess dextensions, and spring pressed outwardly-ad j ustable jaws, pivoted in said recesses, each pr ded with p jecting pi supon opposi sides thereof, said pins upon the opposite vsides, respectively, being of difierent diame' r, substantially as e for h;-

Th m na i n, o a wrench having i stock provided with serrationS 0,1 teeth, and

the movable jaw thereof provided witha proi tins Pill, an a ju t o ar upon h stock, said collar provided with lateral recessed extensions, an d-sprin g pressed and on twardly-adjustable jaws pivoted in said recesses, each provided with projecting pins, and one of said jaws having teeth or serrations engaging theteeth of the stock, substantially as set forth. I

Intestimony whereof I affix my signature in presence of two witneSses.
